Options
3.3.5.1
Cascading
The fresh water station can be cascaded. Cascading is used to pro-
vide drinking water is prepared at peak loads, and to ensure the
operational safety of the drinking water supply. This allows the fresh
water station to be used in large drinking water systems.
The hydraulic interconnections possible for cascading and the corre-
sponding position of the zone valves can be found in the hydraulic
diagram in the annex.
The controller must be connected, and the parameters set, in accord-
ance with the controller instructions.
3.3.5.2
Integrated circulation
The integrated circulation (Fig.
19) is used for drinking water lines
that are long. The drinking water circulates continuously and
shortens the time taken to discharge heated drinking water at the
tap. This allows differences in temperature in the drinking water net-
work connected to be avoided.
Observe the country-specific drinking water guide-
lines.
